I have got used to use RepetierHost -program for printing. I like mostly of its usability and printing preview. I would like to use slic3r- slicer because I like its using logic and how I can save different preferences for different objects, filaments nozzles etc. There is allso cura engine -slicer inside repetier but it's usability is a little bit scrappy I think. Cura -program (15.04) give nice results but I wouldnt like to save the g-code end then print with repetier. But what is the logic of the vertical shells? If we slice 2mm wide object with 0,4mm nozzle shouldnt we have 5 shell layers (with at least 3 layers per side)? Here we have 2mm wide object that allso gets wider with 1mm steps. Pictures: 1.Slic3r 2.Cura engine and 3. Cura -program. Cura engine and Cura program results are pretty much similar as you could expect. But Slic3r does only 4 layers/2mm, 5 layers/3mm and 7 layers/4mm and starts to make infill in 5mm. Curas do 5 layers /2mm and starts infill in 3mm. For some reason in left side there is only 2 layers. edit: curas have 3. layer in left side inside, but it just gets very thin until ends.. Slic3rs infill is allso not dense and 5 layer in 3mm wide object is very not dense. Is Slic3er trying to extruse more material per layer or what?

Here is some pictures of the object that I modeled with Tinkercad for the test. I might print it if it gives some value for the test to see the outcome.

In some cases, yes it does try to extrude a wider line. I'm mobile right now but I'll explain it the best I can. In the settings on slic3r(referencing the prusa edition here), if you browse through some of the default layer widths, you will find as high as .47mm. Another thing I've seen slicing software do is zigzag until into a spot that's more than .4, but less than .8, creating a solid layer without an individual line of filament.

Yes the wider line must be right term.. Had to made some calculations so here we go: Curaengine 405 G1 X102.497 Y101.503 E69.46636 -> 406 G1 X100.497 Y101.503 E69.50618 ->dE=0,03982 -> dE/L=0,01991 407 G1 X100.497 Y83.497 E69.86461 ->dE=0,35843 -> dE/L=0,0199061424 (L=18,006) Slis3r 480 G1 X102.868 Y101.192 E9.45654 481 G1 X102.214 Y101.786 F6000.000 482 G1 X100.214 Y101.786 E9.52182 F2700.000 ->dE=0,06528 -> dE/L=0,03264 483 G1 X100.214 Y83.214 E10.12801 ->dE=0,60619 -> dE/L=0,0326399956 (L=1,8572) 543 G1 X101.500 Y91.196 E14.47690 F1200.000 544 G1 X101.000 Y90.541 F6000.000 545 G1 X101.000 Y87.541 E14.67659 F1200.000 ->dE=0,19969 ->dE/L=0,066563333 Layer height is 0,12mm in both codes so Slic3r sertainly extrudes wider line: about 40% more filament per length (0,032639 vs 0,019906) in shell and in that last strange line infill it again doubles the extrude per length (0,066563).

By the way the filament requirement is Slic3r 316,3mm vs Cura 333mm. Both in 100% infill but the skirt wasn't the same. For some reason my repetier dont show the estimated printing time but I suppose printing the Slis3rs code should be a lot faster becose of less lines: Cura made 6605 g-lines vs. Slis3r 3556.

Yes I found the "Default extrusion width" in Slis3r settings. Just a little strange how wide line it makes when let it count it automatically. Thank you and good night
